I am suffering from muscle twitches, joint pain, and extreme body weakness for over three to four months. My skin has become dry. My finger knuckles have got black pigmentation. My neurologist tells me that my reflexes are normal. I have a history of masturbation from my teenage and I also have the problem of excessive nightfall. Does this problem occur due to any potassium or magnesium deficiency? Or due to any hormonal problem like testosterone or HGH deficiency? My thyroid profile is normal. My brain MRI, EEG, and BP are normal too. I am 5'10" tall and my weight is 174.16 Ibs. I am currently taking tablet Remylin D but there is no improvement. I am also taking Ayurveda remedies for nightfall. Please help to improve my condition.
